Abstract: A solid motor coil with conductive pathways as part of a unitary construction. The conductive pathways are separated by resistive insulating layers. The conductive pathways may vary in their location within the cross-section of the motor coil, which may significantly reduce eddy current losses. The solid motor coil may result in a higher packing factor than previous designs. The solid motor coil may reduce the eddy current loss per conductor, with commensurate reduction in peak temperature rise. An electric motor with solid motor coils provides improved heat conduction and improved efficiency, allowing for a smaller motor package at higher power levels.
